BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a sound control calculator and a use thereof in a pen.

2. Related Art

In daily life, many things are required to be managed by using “calculation” (for example, performing statistics on costs or counting the number of goods). If the calculation is performed by thinking, the process is quite tedious. A “calculator” is one of the most common and convenient tools for calculation. Therefore, calculators are widely used in office affairs, home financing, and shopping settlement. As shown in FIG. 5, the most well-known calculator structure mainly includes a rectangular body (60) having a numeral display screen (61) disposed at a side thereof (generally at an upper portion), and a key set (62) disposed at the rest space. When being used, numeric keys and operation symbols of the key set (62) are pressed to activate an inside operation chip to perform the data operation. Then, the results are displayed on the display screen (61) in the form of numerals. The calculator is criticized in the large volume, for example, the range of the key set (62) of the body (60) in FIG. 5, and the length (63) and width (64) occupy a considerable large position. Therefore, the calculator has the disadvantages of large volume and being inconvenient to carry.

Further, when using a common key-press calculator, the numeric keys of the key set (62) must be pressed by a finger (50) to input, thus errors are inevitable. As shown in FIG. 6, the finger (50) may press two or more numeric keys simultaneously or in a short time, thus wrong information is input. In addition to the increased errors, repeated operation also wastes time, which is the main disadvantage of the conventional calculator. The smaller the calculator is, the more frequently the disadvantage occurs, for example, for the operation function of mobile phones, or mini electronic calculator. Therefore, the calculator with reduced volume is limited by pressing keys to input data, and the situation of pressing the wrong key likely occurs, thus multiple operations must be performed to get a desired accuracy, which is another disadvantage of the conventional calculator.

In a pen calculator disclosed in U.S. Pat. No. 6,104,603, the calculator is attached on an upper part of a pen. However, errors still occur when pressing with a finger, and thus a cap must be used to press. When being used, the calculator must be moved in the axis direction, and the cap is rotated, so as to press the keys of the calculator with the end of the cap. In addition to the inconvenience of inputting numerals in the manner of x-y axis, the keys are easily be pressed by mistake. Therefore, the design is not imperfect. ROC Publication No. 354664 discloses a calculator pen structure for handwriting input. Referring to FIG. 4 of this case (not shown in the present invention), the structure includes a pen tube formed by screwing an upper tube body and a bottom tube base, a pen core disposed at the center. A bottom end of the pen core forms a penpoint, and an expanded oval ball disposed adjacent the penpoint. The oval ball is movably disposed at the bottom of the pen tube and is similar to a universal joint. The pen core has a contact pin, two buffer springs, and a digital plate disposed on the other end thereof. When the penpoint of the pen core writes, the oval ball serves as a fulcrum, such that the handwriting is magnified by the contact pin on the other end due to the lever principle and written onto the digital plate in a reversed manner, interpreted by a recognition circuit and a micro processor, and then displayed by a liquid crystal display (LCD).

The patent seems creative, but it still has the following problems in practice.

1. The pen core is a non-rigid body, when an expanded end is used as a fulcrum at a site near an end of the pen core, and the handwriting is magnified by the other end due to the lever principle, the handwriting is affected by the flexibility, the elastic deformation, and the bend under pressure of the thin and long pen core at the contact pin end. Therefore, the accuracy is doubtful.

2. The penpoint of the pen core is sharp, so it is likely to shake during writing, and the received signal of the handwriting is not clear enough due to the resonance of the two springs, together with the deformation of the pen core.

3. It requires many connection pieces for transferring the handwriting track through the shift of the bar-shaped pen core, and thus the signal is likely to be disordered

4. The digital plate is likely to be damaged when the contact pin scratches thereon.

It can be seen from the patents in prior art that the pen and the calculator are generally assembled together. However, in a general view of the existing patents, no preferred assemble design is provided, and thus the patents are not desired in practical use. The present invention is directed to a indeed novel and practical calculator capable of being applied on a pen, such that the sound control calculator and the pen are assembled into a calculator device facilitate to handwriting, convenient for reading, and accurate in calculating, and more particular, to a convenient and practicable calculator or a pen using the device by assembling a sound control electronic structure.

SUMMARY OF THE INVENTION

The present invention is directed to a fluent and accurate sound control calculator pen. The sound control calculator pen mainly includes a long case with a circuit board disposed therein. The circuit board at least includes a microphone, a recording key, a voice recognition chip, and a display screen for operation. During using, a password can be executed at the microphone. The password is set by the recording key, and is executed through the operation of the voice recognition chip, and then numerals are displayed on the display screen as the operation result. Therefore, the process is rapid, has no errors as in the conventional key-press calculator. The calculator has a small volume, thus being accurate and convenient in use.

The present invention is further directed to a sound control calculator pen has a pen core disposed at an end of a case. The operation results of the sound control calculator mentioned above can be written by a pen end when filling in data, thus being convenient and rapid in use.
